Mimecast

Mimecast is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Mimecast rather than just read about it. In short: Mimecast Limited is a British information security company founded in 2003 and headquartered in London. It is specialized in email security and risk management and is owned by Permira, a British private equity firm.

Key takeaways

Mimecast belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Mimecast to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Mimecast from memory before moving on to harder problems.

Reference excerpt

Mimecast Limited is a British information security company founded in 2003 and headquartered in London. It is specialized in email security and risk management and is owned by Permira, a British private equity firm.

History Mimecast was founded in 2003 by Peter Bauer and Neil Murray. Bauer was named CEO of the company, and Murray was named CTO. The company initially provided cloud-based email management services for Google Workspace, Microsoft Exchange and Microsoft Office 365. In June 2010, Mimecast appointed Dr. Nathaniel Borenstein chief scientist. Borenstein co-created the Multipurpose Internet Mail Extensions (MIME) email standard, along with other email systems and software. Five years later, Mimecast announced its registration statement for a proposed initial public offering (IPO). Mimecast began trading on the Nasdaq Global Select Market under the ticker symbol "MIME" in November 2015. In January 2021, a Mimecast security certificate was compromised, potentially allowing attackers to intercept communications with Microsoft-based email servers. In May 2022, Mimecast was acquired by and become a wholly-owned subsidiary of Magnesium Bidco Limited, an affiliate of Permira Holdings Ltd. In January 2024, Marc van Zadelhoff replaced Bauer as the company's CEO.

Acquisitions In July 2018, Mimecast acquired cybersecurity training start up Ataata. The same month, the company acquired Solebit. In November 2019, Mimecast acquired DMARC Analyzer. The following January, Mimecast acquired Segasec. In January, 2024, Mimecast acquired human risk management specialist Elevate Security.

In July 2024, Mimecast acquired Code42. In August, 2024, Mimecast acquired AI compliance software provider Aware.

Technology Mimecast started as a cloud-based email management platform for Microsoft's email products, and after a series of acquisitions, expanded to be a more general provider of risk reduction services within organizations. Its services include email and collaboration security, insider risk management, data compliance, and security and awareness training.

Operations Mimecast's global headquarters is based in London. Its US headquarters is in Lexington, Massachusetts, just outside of Boston. The company operates additional offices in Bengaluru, Cape Town, Dubai, Hilversum, Israel, Johannesburg, Melbourne, Mississauga, Munich, Paris, Singapore, and Sydney.

Worked examples

Example 1 — a first encounter with Mimecast

Start with the simplest possible case. Write down what Mimecast claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mimecast before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mimecast ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mimecast

In research: Mimecast appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Mimecast in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Mimecast is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2015 initial public offerings, 2022 mergers and acquisitions, Companies formerly listed on the Nasdaq, so understanding it makes those chapters shorter.
In everyday life: Look for Mimecast outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Mimecast in simple terms?

Why does Mimecast matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Mimecast?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
